In this issue, Traub et al. 2005 (p. 2194–2232) have given us a model of a single thalamocortical column. It has 3,560 cells of at least eight types, with up to dozens of compartments, each with many different intrinsic currents. Synapses include AMPA, N-methyl-D-aspartate (NMDA), and GABA receptormediated conductances as well as gap junctions. This is only a fraction of the cells actually foun...

This paper offers new, necessary and sufficient conditions for delay-dependent asymptotic stability of systems of the form 0 1 ( 1) ( ) ( ) x k A x k A x k h + = + − . The time-dependent criteria are derived by Lyapunov’s direct method. Two matrix equations have been derived: matrix polynomial equation and discrete Lyapunov matrix equation. Also, modifications of the existing sufficient conditi...

The DIVA network model is introduced based on the novel computational principle of divergent autoencoding. DIVA produces excellent fits to classic data sets from Shepard, Hovland & Jenkins (1961) and Medin & Schafffer (1978). DIVA is also resistant to catastrophic interference. Such results have not previously been demonstrated by a model that is not committed to both localist coding of exempla...
